Sappi is trading ZAc 1,303.00, up 6.54%, with its gain coinciding with a broader materials-sector rally. - Copper and silver prices climbed amid reduced U.S. rate-hike expectations and potential Chilean mine strikes; the sector rally is a more plausible explanation than company news, though no direct cause is confirmed. - Reuters reported the EU extended the deadline for remedies in Sappi’s proposed paper joint venture with UPM to December 9 amid competition concerns; that news does not clearly explain the gain.
